Add_button_group method

This method is used to add a list of buttons to the toolbar. The buttons are defined in a table of type TTB_BUTTON, and it can be filled witha button definitions using method fill_buttons_data_table of the cl_gui_toolbar class. The button group is added to the toolbar using method add_button_group of the toolbar object.

Advanced example

The toolbar in this example contains an Exit button, two buttons that enables/and disables a Print button, and a Menu button with a context menu.

The Disable/Enable buttons are of type Pushbutton group which makes them act together, so when one of the buttons are selected (Down) the other is deselected (Up).

Note that the context menu for the Menu button, must be created as a GUI status. You can create an empty GUI sttaus of type context, and then manually

add menus. The context menu instance is created with type reference to class cl_ctmenu.

Steps:

Create a screen and add a custom container named TOOLBAR_CONTAINER

Create a GUI status of type Context and name it TOOLBAR. Note that you can not add any buttons to the GUI sttaus at design time.

The screen:

In this screen shot the Disable button is activated which makes the Print button disabled:

This screenshot shows the context menu and sub menu:
